Abstract
1483037 Purifying combustible gases METALLGESELLSCHAFT AG 8 July 1975 [29 Jan 1975] 28771/75 Addition to 1483038 Heading C5E The process for purifying a gas produced by the gasification of a solid or liquid fossil fuel in the presence of steam and/or oxygen under superatmospheric pressure described and claimed in the parent Specification is improved or modified by the steps of regenerating the scrubbing agent which has been used in the second scrubbing stage by flashing it approximately to atmospheric pressure, heating the scrubbing agent to the boiling temperature in the presence of sufficient water, if necessary, to ensure that the boiling temperature is not in excess of 170 C., treating the scrubbing agent in a stripping column with steam or stripping gas to remove the liquid impurities, condensing the mixed vapours, isolating the condensates by phase separation, feeding part of the aqueous phase as a reflux to the upper portion of the stripping column, cooling the stripped scrubbing agent and feeding it back for use in the second scrubbing stage. Embodiments of the regeneration procedure are described in detail. Organic solvents: N-methyl-pyrrolidone or other N-alkylated lactam, and polyalkyleneglycoldimethylether or other water soluble glycol ether having a boiling point below 200 C.
